Note:
1. Reference signal is defined as O-QPSK DSSS per 802.15.4, Frequency range = 2400-2483.5 MHz, Symbol rate = 62.5 ksym-
bols/s
2. Receive sensitivity on 802.15.4 channel 14 is -98 dBm
3. Reference sensitivity level is -85 dBm
4. Filter is characterized as a symmetric bandpass centered on the adjacent channel having a 3dB bandwidth of 4.6 MHz and stop-
band rejection better than 26 dB beyond 3.15 MHz from the adjacent carrier.
5. Due to low-IF frequency, there is some overlap of adjacent channel and image channel bands. Adjacent channel CW blocker
tests place the Interferer center frequency at the Desired frequency ±5 MHz on the channel raster, whereas the image rejection
test places the CW interferer near the image frequency of the Desired signal carrier, regardless of the channel raster.
